Billy met former financial advisor Alexis in 2009. The couple then got married in 2015 and celebrated their second wedding anniversary this year. The pair are now settled in New York as they wait for their new baby to arrive.

When asked about becoming a father again in his 60s before the birth of his second child Della, the singer said he was ‘excited’ and wanted to use his age as an advantage to spend more time at home with his children.

‘I’m gonna spend a lot of time with this kid,’ he said. ‘I was thinking about that. I’m probably going to be able to spend more time with this kid than most people are able to spend with their children, because I don’t have a regular job. I could be a stay-at-home dad for as long as I can stay alive.’
